Description:
Nico Leidecker has reported some vulnerabilities in SurgeFTP, which can be exploited by malicious people to conduct script insertion attacks and cause a DoS (Denial of Service).
1) SurgeFTP does not handle malformed responses to the "PASV" command correctly when connecting to a mirrored server. This can be exploited to crash the service by sending specially crafted responses to the "PASV" command.
2) The web interface of SurgeFTP does not properly sanitise certain status messages before using them. This can be exploited to execute arbitrary HTML and script code in an administrators browser session in context of the web interface by sending specially crafted status messages that do not start with a numeric value.
The vulnerabilities are reported in version 2.3a1. Other versions may also be affected.
Solution:
Reportedly, the vulnerabilities have been fixed. Contact the vendor for further details.
